What is the range of the function f(x) = |x| – 3?

Likurg_2 [28]

Why not draw the graph of y=|x|? It has a v-shape, and the vertex is at (0,0).

The graph of f(x) = |x| - 3 looks exactly the same, EXCEPT that the whole graph of |x| is shifted 3 units downward. The smallest value that y can have is therefore -3.

Can you now figure out the range of f(x)?

1. Eight people work in an office. They are paid hourly rates of 12£,15£,15£,14£,14£,13£,14£,13£

bearhunter [10]

Answer:

mean=110/8 =13.75 pounds; median=14 pounds; mode=14 pounds; average=13.75 pounds

Step-by-step explanation:

mean=add all the numbers together to get total then divide that total by the number of amounts present 12, 15, 15, 14, 14, 13, 14, 13 =110, then 110/8=13.75 pounds

mode=arrange amounts in order (smallest to largest), then determine which amount appears more than the other amounts 12, 13, 13, 14, 14, 14, 15, 15 =14 appears the most

median=organize numbers from smallest to greatest, count how many there are, then determine which number appears in the middle of all of them 12, 13, 13, 14, 14, 14, 15, 15 = there are 8 numbers present but 14 is in the middle; answer =14

average= take total of mean, then divide it by the number of amounts that appear 110/8 =13.75

SALARY In a recent year, the median salary for an engineer in the United States was $55,000 and the median salary for a computer

dalvyx [7]

Given :

Median salary of engineer , E = $55,000 .

Median salary of computer engineer , C = $52,000 .

To Find :

The total cost for a business to employ two engineers and three programmers for 1 year .

Solution :

Now , cost of paying two engineers .

$C_e=\$2\times 55000\\\\C_e=\$110000$

Also , cost of paying three programmers .

$C_p=3\times 52000\\\\C_p=\$156000$

Therefore , total cost for 1 year is $\$(110000+156000)=\$266000$ .

Hence , this is the required solution .

Choose the equation for the relationship shown in the graph.

uysha [10]

Answer:

B) y = x - 50

Step-by-step explanation:

It is B because the graph's y-intercept lies on the point (0, -50), hence the equation, y = x <u>- 50</u>. In addition, you can verify that B is the correct answer because the slope of the graph is positive, and so the x-value also must be positive.
